New design already implemented

However, Motorola plans to appeal the verdict and says that it has already has an alternative phone unlock method in place, so expects no ban to ever come into effect.

A Moto spokeswoman said: "Today's ruling in the patent litigation brought by Apple in Munich, Germany, concerns a software feature related to phone unlocking in select Motorola devices sold in Germany.

"Motorola has implemented a new design for the feature. Therefore, we expect no impact on current supply or future sales."

Yet more lawsuits

However, with the appeals and counter appeals set to rumble on, the Munich victory will probably open the door for Apple to challenge more manufacturers carrying the Android operating system and using slide-to-unlock.

Motorola may also become the chief target of Apple's legal wrath once it is officially acquired by Google.
